The air inlet 106 communicates with the bottom of the furnace body 10 through an air inlet passage 107 of the rear side 102 of the furnace body 10. The exhaust port 105 and the air inlet 106 are connected to a pipeline A. The pipeline A is composed of inner and outer tubes A1 and A2. The inner tube A1 communicates with the air outlet 105, and the outer tube A2 communicates with the air inlet 106. .

A partitioning member 14 is disposed in the furnace body 10. The partitioning member 14 includes a partitioning plate 141 and two vertical plates 142. The partitioning plate 141 is connected to a wall surface of the furnace body 10, and the partitioning plate 141 has a The opening 143, the two vertical plates 142 are disposed at the opening 143. The intake passage 107 communicates with a space below the partition plate 141.

The burner 20 is disposed at the bottom of the furnace body 10 and below the partition plate 141 and corresponds to the opening 143 for burning gas. The burner 20 has an elongated shape extending from the left side 103 of the furnace body 10 to the right side 104 of the furnace body 10. The flame generated by the burner 20 burning the gas extends from between the two vertical plates 142 to above the partition plate 141.

The air guiding device 30 is coupled to the inner wall of the furnace body 10 and located between the exhaust port 105 and the burner 20, and the air guiding device 30 divides the interior of the furnace body 10 into a first space S1 and a first Two spaces S2, the first space S1 communicates with the exhaust port 105, and the partition 14 and the burner 20 are located in the second space S2. The air guiding device 30 includes a first guiding plate 32, a second guiding plate 34, a plurality of partitions 36 and a baffle 38. The first guiding plate 32 and the second guiding plate 34 are inclined from the top to the bottom by the center of the furnace body 10 toward the front side 101 and the rear side 102, respectively.

The first guiding plate 32 has a first top edge 321 and a first guiding surface 322. The second guiding plate 34 has a second top edge 341 and a second guiding surface 342. The first and second top edges 321 and 341 are spaced apart from each other and extend parallel to each other and extend in a direction parallel to the burner 20, and the first top edge 321 is positioned higher than the second top edge 341. The two guiding surfaces 322 and 342 are oriented toward the second space S2, and a channel 40 is formed between the two guiding surfaces 322 and 342 to communicate with the first and second spaces S1 and S2. The width of the channel 40 in the direction of the front side 101 toward the rear side 102 is gradually decreased from bottom to top, and an outlet 42 is formed between the first and second top edges 321 and 341 to communicate with the channel 40 and the first Space S1. The outlet 42 is located directly above the burner 20 and has a long axial direction parallel to the direction of extension of the burner 20, wherein the width of the outlet 42 in the long axis is greater than the burner 20 The length in the direction of its extension.

The partitions 36 are disposed at intervals along the outlet 42 . Each of the partitions 36 is coupled to the first guiding plate 32 and the second guiding plate 34 , and perpendicular to the two guiding surfaces 322 and 342 . . The baffle 38 is fixed to the second top edge 341 of the second guiding plate 34 and located between the two partitions 36 closest to the exhaust port 105 and corresponding to the exhaust port 105. The two partition plates 36 are symmetrically disposed left and right with the baffle 38 as a center, so that the distance between the two partition plates and the baffle plate are the same.

5 and FIG. 6, when the burner 20 burns gas, the generated hot gas flow flows upward from the second space S2, and passes through the outlet 42 as the two guiding surfaces 322, 342 pass upward. Flow into the first space The interval S1 is further discharged from the exhaust port 105. Since the widths of the two guiding surfaces 322 and 342 are gradually reduced from the bottom to the top, the flow velocity of the airflow can be slowed down, so that the hot air can smoothly enter the first space S1, and the turbulent flow in the second space S2 is reduced. The opportunity is to prevent the hot air from remaining in the second space S2, and the temperature of the second space S2 is too high. When the hot gas rises to the first space S1, its hot gas flow rate is slow, and thus it can be discharged to the exhaust port 105 relatively easily.

The combustion air entering from the air inlet 106 of the furnace body 10 is supplied by the combustion air below the partition plate 141, and therefore does not affect the flow of the airflow above the partition plate 141. In addition, the baffle 38 of the air guiding device 30 is located at the corresponding exhaust port 105, so that the upwardly rising hot gas can be blocked from concentrating in the channel 40, that is, toward the exhaust port 105, so that the hot gas can be dispersedly passed through the air. Between the partitions 36, the chance of turbulence is reduced. The two partition plates 36 are symmetrically disposed left and right with the baffle 38 as a center, and the passing airflow can be uniformly entered into the first space S1 from the left and right sides of the baffle 38.

The gas fireplace 200 of the present invention smoothly discharges the hot air inside the furnace body 10 to the outside by the air guiding device 30 having a gas guiding effect, thereby reducing the heat accumulated in the second space S2, compared with the conventional one. A gas fireplace can reduce the temperature of the tempered glass 12.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present invention and the scope of the patent application are intended to be included in the scope of the present invention.
